DESCRI PTI O N
The LX1562 is a second-generation
family
of
power
factor
correction
controllers using a discontinuous mode of
operation.
They
are
optimized
for
electronic
ballast
applications.
Many
improvements have been made over the
original SG3561A controller introduced by
Silicon General Semiconductor in 1992.
New features include the addition of an
internal start-up circuit eliminating bulky
external
components
while
allowing
independent
boost
converter
operation.
Addition of internal current sense blanking
eliminating the need for an external R/C
filter network.
Internal clamping of the
error
amplifier
and
multiplier
outputs
improves turn on overshoot characteristics
and current limiting.
Special circuitry has also been added to
prevent no load runaway conditions. And
finally, output drive clamps limiting power
MOSEFT gate drive independent of supply
voltage
greatly
enhance
the
products
practical application.
Although
the
IC
design
has
been
optimized
for
electronic
ballast
applications, it can also be used for power
factor correction in lower power (typical <
300W) AC-DC converters.
One unique
feature of the device is encompassed by
the addition of internal logic circuitry to
detect zero crossing of the inductor current
thus maintaining the discontinuous current
mode of operation. This feature prevents
large current gaps from appearing thereby
minimizing
distortion
and
enhancing
power factor correction.
